Three new features are available on this one , active track which works really well, tap fly, and collision avoidance. The collision avoidance works really well too, it sees people, bushes, trees, houses, poles, etc. Sport mode is another amazing featurelso the hover accuracy is like 5 times better than the previous versionsAnd the shell of the phantom 4 is probably 10 times stronger than the phantom 3 pro. The propellers are really easy to put on and take off, also the camera is much more stable then the phantom three professional, also the battery life is five minutes longer
